What does a pressure swing adsorption air separation unit look like?

       Pressure Swing Adsorption Air Separation EquipmentAfter the air passes through the air filter to remove dust and impurities, it enters the air compressor and is compressed to the required pressure. After rigorous oil removal, water removal, dust removal, and purification, clean compressed air is output to ensure the service life of the molecular sieve in the adsorption tower.

       There are two adsorption towers containing carbon molecular sieves. When one tower is working, the other tower is depressurized and desorbed. Clean air enters the working adsorption tower, and oxygen, carbon dioxide, and water are adsorbed by the molecular sieve as they pass through. The gas flowing to the outlet is nitrogen and trace amounts of argon and oxygen. The other tower (desorption tower) releases the adsorbed oxygen, carbon dioxide, and water from the micropores of the molecular sieve and discharges them into the atmosphere. In this way, the two towers operate in turn to complete nitrogen-oxygen separation and continuously output nitrogen. Jiayu CMS  PSA nitrogen generator has a nitrogen output of 1-3000 Nm3/h, and the nitrogen exposure point is -40.

　　 Pressure Swing Adsorption Air Separation EquipmentOperating Characteristics:

　　1. The purity of nitrogen produced by pressure swing adsorption air separation equipment is 97%-99.9%. If higher purity nitrogen is required, nitrogen purification equipment can be added. The 97%-99.9% nitrogen output from the pressure swing adsorption air separation equipment enters the nitrogen purification device, and an appropriate amount of hydrogen is added through a *meter. In the oxygen removal tower of the purification device, hydrogen reacts with trace oxygen in the nitrogen to remove oxygen, then it is cooled through a water cooler, dehydrated through a gas-water separator, and then deeply dried through a dryer (two adsorption drying towers are used alternately: one adsorption drying dehydration).

2. When the pressure swing adsorption method is started, press the button, and qualified nitrogen products can be obtained within 30 minutes. If high-purity nitrogen is required, it can be obtained after about 30 minutes through the nitrogen purification device, and 99.99%-99.9999% high-purity nitrogen can be obtained. When stopping, just press a button once. Therefore, pressure swing adsorption air separation equipment is suitable for special situations with intermittent operation.

　　Laboratory pressure swing adsorption air separation equipment is mainly used for school laboratory teaching. Beverages are preserved through easy-open cans. Using carbon molecular sieve as the adsorbent, under a certain pressure, oxygen and nitrogen in the air have different diffusion rates in the pores of the carbon molecular sieve, thus achieving the purpose of separating air. This beverage has the characteristics of normal temperature production, simple process, high degree of automation, low vulnerability, convenient shutdown, easy maintenance, and low production cost.

　　The laboratory liquid nitrogen generator is a nitrogen generation equipment designed and manufactured based on pressure swing adsorption technology. It helps ensure smooth air flow in the system, can reduce the discharge temperature of compressed air, and separates water, oil, and other impurities from the compressed air according to the decrease in compressed air temperature. This helps to extend the service life of the post-processing equipment and improve the quality of the compressed air.

　　The laboratory pressure swing adsorption air separation equipment adopts a special process to fill the molecular sieve, gas grading design, high adsorption rate, and effectively prevents molecular sieve differentiation. Three-stage filtration, pneumatic angle valve control, PLC microcomputer automatic control, 3 million times of failure-free operation, and remote computer online control.

 LaboratoryPressure Swing Adsorption Air Separation EquipmentDuring long-term use, maintenance should be paid attention to in order to extend the effective life of the equipment.

1. During operation, if a large amount of black dust is found in the cavity, the cause should be stopped and found immediately to prevent further aggravation of carbon molecular sieve pulverization.

　　2. Carbon molecular sieve is its core. In order to prevent pollution and loss of function, the oil content in the air compressor exhaust gas needs to be strictly controlled, and the precision filter element and activated carbon in the high-efficiency oil remover should be replaced regularly.

3.Pressure Swing Adsorption Air Separation EquipmentRegularly check the pressure gauge of the compression cylinder. If there is no pressure or pressure drop during desorption, the cylinder cannot press the carbon molecular sieve normally, and the carbon molecular sieve cannot be moved. Therefore, the problem needs to be solved promptly to avoid the generation of molecular sieve powder. When the carbon molecular sieve gap is reconstructed or normal wear and tear causes a carbon level alarm, adding carbon molecular sieve must be stopped immediately. The storage, transportation, and handling of carbon molecular sieves are harmless to the human body. When filling carbon molecular sieves, wear goggles, a respiratory filter, and an exhaust fan, and clean the skin contact area with soap after filling.
